Detailed description of the invention

All features disclosed in this description, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.

One. the basement principle of jasmine tea and program basement principle: scented tea baking process mainly fresh flower tells the process that fragrant and tea embryo enfleurages.The perfume (or spice) of telling of jasmine fresh flower is biochemical change, and ripe Jasmine, under the effects such as enzyme, temperature, moisture content, oxygen, decomposites fragrant material, along with physiological change, and the opening of flower, and the fragrance that constantly spues.It is under physisorption that tea embryo is enfleuraged, also absorb a large amount of moisture content along with enfleuraging simultaneously, due to the osmosis of water, create chemisorbed, under hyther, there occurs complicated chemical change, millet paste from green turn yellow gradually bright, flavour has and lightly puckeryly transfers dense alcohol to, forms the perfume (or spice) of distinctive jasmine tea, look, taste.Basement processing procedure sequence: the basement traditional handicraft program of jasmine tea: tea embryo, flower are spelled and heap basement logical flower closing heap rockets cures cooling and turn basement or the even heap of jacquard weave, vanning.

Two. the tea embryo of tea embryo process scenting tea forms according to jasmine tea tea embryo level type standard sample is assorted through refining (summary) with green gross tea.1, dry: the tea embryo of scenting tea generally will through super-dry process.Object: high-grade tea embryo is to distribute water sulks, old taste; Low and middle-grade tea embryo is to reduce thick old taste, old taste etc., manifests normal green tea fragrance, and the fresh purity being conducive to jasmine tea improves.Dryer temperature generally should not be too high, and high-grade tea embryo is at 100-110 DEG C, and low and middle-grade tea embryo can at 110-120 DEG C.Traditional handicraft requires to dry rear tea embryo moisture content 4-45%, and high fire can not be used to dry, and the fiery smell of burning of easy generation, affects quality of flower tea.2, cool: after tea embryo complex fire, general heap temperature is higher, at 60-80 DEG C, must pass through spreading for cooling, cooling, basement could be paid when the warm tip high room temperature 1-3 DEG C piled by tealeaves, too highly carry out basement system, affect Jasmine life and tell perfume (or spice), reduce quality of flower tea, tea embryo temperature is more low better, such basement system spell and after, make heap temperature rise slowly, the heap temperature time of relative prolongation 32-37 DEG C, be conducive to fresh flower to tell fragrant and tea embryo and enfleurage, raising jasmine tea quality.

Three. fresh flower maintenance Jasmine has open to tell fragrant habit night, fresh flower generally that afternoon two time after pluck, bud is large, output is high, quality is good.After gathering, do not press during shipment, spend as well with the large bamboo or wicker basket dress of ventilation, must guard against with plastic bag, easily extrude, stuffiness, easily cause " burning flower ".1, spreading for cooling: fresh flower is marched into the arena and adapted to check and accept in time weigh, by fraction heap, spreading for cooling (classification standard refers to attached).Object is: fresh flower is in transport process due to dress pressure, and respiration produces heat, not easily distributes, and makes flower temperature rise, generally all more than 38 DEG C, high more than 40 DEG C.Unfavorable fresh flower physiological activity, necessary spreading for cooling rapidly, makes its radiating and cooling, recovers life, promotes to open to tell perfume (or spice).Spreading for cooling place must ventilate totally, and during spreading for cooling, flower heap is thin, generally at below 10cm.During temperature height, available light-duty fan blowing; Rainwater flower, more wants thin stand, blowing, and evaporation flower surface water, after surface water is dry, could pile up maintenance.2, fresh flower maintenance: object is to control the temperature in flower heap, makes fresh flower life vigorous, promotes to open and fiercely tells perfume (or spice).The open preference temperature of fresh flower is at 32-37 DEG C, and therefore, temperature, must flower heap Gao Cuiwen lower than 30 DEG C, fresh flower respiration is released CO2 and is produced heat, and flower stack temperature is raised, when heap temperature reaches more than 38 DEG C, flower heap will be pushed aside, the cooling of thin stand, and increase oxygen and promote that fresh flower is open; Want thin stand during temperature height, stir, ventilate, prevent the warm too high fresh flower of heap from going bad, the high 15-20cm of general heap.Spring, autumn, because temperature is low, the high 30-40cm of general heap, also covers with cloth sometimes, keeps heap temperature, promotes that fresh flower is open.3, sieve flower: the open rate of fresh flower, about 60% time, can sieve flower, and the object of sieve flower is potted flower size, rejects the blue or green flower bud base of a fruit; By mechanical oscillation, the open healthy tendency of fresh flower can be promoted again.The branch that should weigh by each batch of predetermined distributing cotton quantity after fresh flower sieve is stacked, if openness should continue maintenance not.Fresh flower uses: a flower is used for jacquard weave, turns basement and senior tea head basement; No. two flowers are used for head basement.If have one, No. two flower for the same batch tea time, then first use No. one, No. two, rear use, must not use with, separate basement.4, yulan bottoming.Object is with fresh yulan " blending ", improves the concentration of jasmine tea fragrance, the fresh degree of " setting off " fragrance of a flower.Appropriateness is grasped in bottoming, can improve jasmine tea quality.Method of priming: at basement jasmine tea, tea, flower are spelled and front yulan fresh flower (generally using 1%, tea 100kg yulan fresh flower 1kg) of first using first is spelled in tea embryo and carries out " bottoming "; Have when basement Jasmine, spell as yulan fresh flower, but consumption is not easily too much simultaneously, many easily causes " thoroughly orchid "; Have when jacquard weave again with a small amount of yulan fresh flower and Jasmine spell with together with carry out jacquard weave (consumption 03-05%).

Four. basement flower is spelled and basement flower is spelled and makes whole jasmine tea basement process key procedure.Object utilizes together with fresh flower mixes and stirs with tea, allow fresh flower tell perfume (or spice) directly absorb by tealeaves.Basement spends spelling and GPRS six factors: distributing cotton quantity, spend openness, temperature, moisture content, thickness, time.

Five. scenting tea manual manipulation method is first tea embryo total amount 1/3-1/5, divide on clean basement flower place, thickness is 10-15cm, then according to the fresh flower of tea, flower proportioning consumption, separate 1/3-1/5 equally to spread uniformly and be layered on tea embryo face, such one deck tea, one deck spends alternate 3-5 layers, more from top to bottom to push aside from cross section with creeper and mix and stir.Tea embryo and fresh flower are mixed while undertaken " basement flower " by case basement, village basement, block basement method.Tea, flower spell and after, to throw in wooden case (wooden case specification 46 × 43 × 43cm i.e. No. two Standard China Green Tea casees) basement flower and be case basement.Be applicable to basement flower measure less or extraordinary jasmine tea.Every case basement tea amount is about 5kg, thickness 20-30cm.Case keeps flat arrangement or intersects and stacks, in order to air circulation.With the honest and clean circle of high 40-60cm bamboo Flower and tea mixer and after to be deposited in circle basement flower and to cry and store up basement, be applicable to medium quantity batch processing, store up diameter 150-200cm, often grain bin basement tea amount 200-300kg.Tea, flower are spelled and become block basement flower to be block basement or heap basement with the rear ground that is directly deposited in, and be applicable to produce in enormous quantities, heap rectangularity, wide 1-12M, length is determined according to place and basement amount, often piles 600-1000kg.Heap basement, saving of labor, rapid, convenience, current scented tea baking normally adopts heap basement.In addition, all will with the very thin distribution one deck of the tea embryo of this batch in the heap face of basement product, thickness is about 1cm, reaches fresh flower and does not expose, and scatter and disappear to reduce the fragrance of a flower, this operation is called " capping ".Under natural conditions and normal temperature (32-37 DEG C), Jasmine tells the fragrant duration and generally can reach 24 hours.Fresh flower and tealeaves spell and basement time, owing to being pressed in Hua Cha, eupnea effect is subject to certain obstruction, fresh flower life shortens, and tells the fragrant duration generally at 12 hours, as can be seen from observation and test, Jasmine starts to tell in fragrant 5 hours later as telling fragrant animated period, now, respiration intensity is large, and dry loss is also many, the volatilization of aromatic oil is also fierce, so tell aromatic strong time, flower and tea must be spelled in time and with basement system, in order to avoid fragrance scatters and disappears in a large number.Therefore, grasp Jasmine openness, spell rapidly and basement system, offer embryo tea and fully absorb the key that the fragrance of a flower is whole scenting process technology.

Six. the loose logical object spending the logical flower heat radiation of heat: is radiating and cooling; Two is ventilation oxygen supply, promotes that fresh flower recovers life, continues to tell perfume (or spice); Three is distribute carbon dioxide in heap and other gases.Ricepaperplant root is grasped according to the life state at basement product heap temperature, moisture content and fragrant flower, from basement flower to the logical basement 5-6 hours of taking time, shortens half an hour by basement.The closing heap time mainly reaches requirement depending on the decline of heap temperature and gets final product closing heap (for details see attached table), and logical flower heat radiation is exactly the tea at basement is piled push spreading for cooling aside, from the high 30-40cm of heap, push high about the 10cm of thin stand heap aside, every 15 minutes, then turn once, offer heap fully heat radiation tea, when about 1 hours heap temperature reaches requirement, with regard to the multiple basement of closing heap, heap height about 30cm, then through 5-6 hours, tea stack temperature rose to again about 40 DEG C, spend the tune shape that become to wither, color and luster, by turning micro-Huang in vain, is smelt less than fresh perfume (or spice), can be rocketed.

Seven. rocketing reaches 10-12 hours in the basement time, and flower is by devitalization, and tea embryo absorbs moisture content and fragrance when arriving certain state, must rocket immediately, with the machine of rocketing tea and flower separately, namely cry and rocket.The order that rockets is " many basements time first rise, and rise after low basement time, with basement time first senior tea, rear rudimentary tea ".As do not rocketed in time, then under hydrothermal, flower slag turns yellow and ripely presents vexed yellow taste, alcohol smell, affects jasmine tea quality.If the same day, basement quantity was many, have little time at short notice to rocket, must flower heap be pushed aside heat radiation.1, according to the heap temperature at basement product, grasp and rocket in good time.Head basement 41 DEG C, two basements 40 DEG C, decline by basement, jacquard weave 38 DEG C, when heap temperature exceedes, if the time does not also arrive, must carry out the logical flower of second time or turning heat radiation.According at basement product moisture content, grasp and rocket in good time: head basement 17-18%, two basement 13-14%, three basement 11-12%, jacquard weave 85%.Rocket operation: operation is wanted rapidly, accomplishes in tealeaves without the flower base of a fruit, floral leaf after rocketing; Without tealeaves in flower slag.After shutdown, screen cloth must clean totally, and the wet tea after rocketing wants the thin stand anti-sealing of heat radiation to boil in a covered pot over a slow fire taste.2, cure object to be to get rid of excessive moisture, keep suitable water content, adapt to subsequent processing and turn basement, jacquard weave or vanning.Basement product cure again, require fast, prevent the fragrance of a flower to scatter and disappear again to greatest extent, solve this contradiction, mainly grasp the temperature of drying hot blast by correct, and tea moisture content after baking.Controlling tea moisture content regulates stoving temperature as follows: the necessary fully spreading for cooling of tealeaves after drying, and some utilizations are carried for a long time, and what have carries out with spreading-and-cooling machine, but forbidding high wind blows, cause fragrance unnecessary scatter and disappear, the tealeaves temperature after spreading for cooling is more low better, the highest must not more than 40 DEG C.3, embossing embossing utilizes the colored slag basement low-grade tea again after rocketing, and object is the lingering fragrance making full use of colored slag, and the thick old taste forcing down low-grade tea increases the fragrance of a flower.(1) flower will be accomplished in time rapidly, accomplishes that lace embossing is played on limit.(2) the colored slag of jacquard weave still pure white fragrance pure to tell fragrant ability still strong, can press middle-grade tealeaves, all the other normally spend slag for low-grade tea embossing, but flavescence of becoming thoroughly decomposed, smelly colored slag can not be used for embossing.(3) spend slag consumption: 40-50kg flower slag generally used by 100kg tealeaves, pressure once can support the fresh flower distributing cotton quantity of 5kg.(4) embossing time, rests in 4-5 hours, and unsuitable long, taste, ferment taste and other peculiar smell are boiled in a covered pot over a slow fire in oversize place of causing, and should play colored slag in time, tea also must cure in time.4, jacquard weave jacquard weave object is the fresh degree improving jasmine tea, operates same basement flower.(1) the jacquard weave flower that a large pure white fragrance is strong, rainwater flower can not be used.Mix and stir rear heap basement, owing to taking time short (6-8 hours basement time of heap) with few (the general 100kg tealeaves 6-10kg spends) basement of the amount of spending, heap Wen Bugao need not carry out logical flower.
